The 15-Country Collaborative Study of Cancer Risk among Radiation Workers in the Nuclear Industry: estimates of radiation-related cancer risks.

A 15-Country collaborative cohort study was conducted to provide direct estimates of cancer risk following protracted low doses of ionizing radiation. Analyses included 407,391 nuclear industry workers monitored individually for external radiation and 5.2 million person-years of follow-up.

The 15-Country Collaborative Study of Cancer Risk among Radiation Workers in the Nuclear Industry: study of errors in dosimetry.

To provide direct estimates of cancer risk after low-dose protracted exposure to ionizing radiation, a large-scale epidemiological study of nuclear industry workers was conducted in 15 countries. As part of this study, identification and quantification of errors in historical recorded doses was conducted based on a review of dosimetric practices and technologies in participating facilities. The main sources of errors on doses from "high-energy" photons (100-3000 keV) were identified as the response of dosimeters in workplace exposure conditions and historical calibration practices.

Risk of cancer after low doses of ionising radiation: retrospective cohort study in 15 countries.

Objectives: To provide direct estimates of risk of cancer after protracted low doses of ionising radiation and to strengthen the scientific basis of radiation protection standards for environmental, occupational, and medical diagnostic exposures.

Design: Multinational retrospective cohort study of cancer mortality.

Setting: Cohorts of workers in the nuclear industry in 15 countries.

The monetary value of the person-Sievert: a practical approach in case of occupational exposures.

This paper gives some practical advice on the determination of the value of the person-Sievert, this figure being of primary importance when cost-benefit analysis is used to optimize (ALARA-principle) routine occupational exposures of professionals to external radiation. After a brief introduction on the use of cost-benefit analysis in a radioprotection context, more attention will be paid to the theoretical guidelines that exist on the monetary value of the person-Sievert. By combining these insights with the practical problems that occur in daily task preparations and evaluations, a more workable proposal for the determination of the value of the person-Sievert will be presented.
